Abstract: A controlled temperature unit is disclosed herein. The various components of the controlled temperature unit allow the unit to control temperature and collect or manage temperature data in a novel and unique manner to fulfill an unmet need. The controlled temperature unit may be equipped with multiple temperature probes, and data generated by these probes may be managed by a process control unit housed within the wall of the controlled temperature unit. The process control unit may then be operable to display temperature related data on a visual display attached to one of the exterior walls of the controlled temperature unit. The scope of the present disclosure extends to all mechanical and electrically automated engineering features that may extend the lifespan of the validated state of a CTU.
